作為魯迅的伴侶，許廣平對魯迅日常生活的近距離觀察，使她成為書寫魯迅「私密的個人史」的最佳人選。然而，建國後許廣平的魯迅紀念，卻放棄了早年對魯迅私人生活的瑣屑筆錄，從微觀歷史走向宏大敘事，利用她與魯迅的私密關係，將「魯迅」納入「文革」大歷史中，極力促使魯迅成為「公物」，進一步成為政治意識形態的工具。總體上，許廣平建國後，尤其是「文革」中的魯迅紀念，大「公」無「私」，甚至假「私」濟「公」，塑造了一個「被虛構的魯迅」。

Xu Guang-ping closely observed Lu Xun's daily life, which made her the best person to write Lu Xun's personal narrative. However, since the founding of the country in 1949, Xu Guang-ping gave up the early trivial record about Lu Xun's personal daily life, and started the grand narrative from the micro history using Xu and Lu's intimate relationship. Xu brought Lu Xun into the "Cultural Revolution" history and made Lu Xun a public property, a political and ideological tool. As a whole, since 1949, Xu Guang-ping figured an imaginary Lu Xun.
